“"The V-tail that outlived every fashion trend in aviation."”
On 22 December 1945, with Wichita practically shut down to watch, test pilot Vern Carstens lifted the Beechcraft Model 35 into a winter sky. The V-tail—dubbed the butterfly—was a statement: two surfaces doing the work of three, saving weight and drag while looking unmistakable. Walter Beech wanted a four-seat luxury sedan that happened to fly 175 mph; what he got was a machine that would still be in production eight decades later. The CAA issued Approved Type Certificate A-777 on 25 March 1947, and 1,500 orders poured in before the first one left the factory at $7,975. William Odom later flew a Bonanza nonstop from Hawaii to New Jersey. More than 17,000 have been built, and the name remains synonymous with the ultimate single-engine cross-country machine.
The Bonanza’s V-tail was controversial from the start and was eventually retired for safety concerns. How does a design feature that is aerodynamically elegant become operationally problematic over decades?
